'Breaking Bad' Season 4 Premiere: What Viewers Are Saying

"Cougar Town" co-creator Bill Lawrence and "Lost" co-creator Damon Lindelof are among those weighing in on the AMC drama series opener.

Breaking Bad is back.

The AMC drama series had its fourth-season premiere Sunday night.

THR chief TV critic Tim Goodman says the show is darker than ever thanks to the "genius" of creator Vince Gilligan.

"Audacious doesn't even begin to cover what this man is doing," he wrote. "Gilligan is attempting (and has succeeded over the course of three brilliant seasons) a kind of confrontational transformation that should, using conventional logic, alienate his core audience and not only slay the golden goose but light it on fire as well. You don't take your main character and make him unlikable. You just don't. Nobody does that. Nobody has ever really done that to this extent."
